+=head3 select- version works fine, but things go awry when I use a textbox, any idea?
+
+If there is more than one match, check_name will display a select form, that
+will redirect to the original C<nextsub>. Unfortunately any hidden vars or
+input fields will be lost in the process unless saved before in a callback.
+
+If you still want to use it, you can disable this feature, like this:
+
+ check_name('customer', no_select => 1)
+
+In that case multiple matches will trigger an error.
+
+Otherwise you'll have to care to include a complete state in callback.
